Cryptopus brachiatus H.Perrier, Notul. Syst. (Paris) 7: 137 (1938).
Description:
Plants with abort stems (5-10 cm long), sometimes branching, heavily sinuate, 3-4 mm, in diameter; sheaths heavily striate-veined; leaves 4-5, apical on the stems or branches, distant, elliptical-oblong (1.5- 5.6 x 1.2 cm), attenuate-obtuse toward both ends, thick and coriaceous. Inflorescences from in the sheaths, 7-16 cm long, 5-10 flowered, loosely arranged; peduncle short (2-5 cm long), rigid, upright, clad with 2-3 short sheaths; bracts short (a slight 1 mm long), obtuse; pedicel joined as those in the Aerangis, with a short articulation, slightly above the bract. Sepals narrowly obovate-cuneiform (1.3-1.4 cm x 4.5mm), obscurely many veined, the laterals narrower than the median. Petals narrowly oblanceolate, linear, 4 cm tall, divided into 2 horizontal-linear lobes apically, 8-10 mm long (or in the form of a T, with the horizontal bar longer than the vertical). Labellum narrowed basally, joined to the front of the spur oriface. then deeply trilobed, lateral lobes obovate-cuneiform (12 x 5 mm), unequaliteral, with 7-8 very divided veins: median lobe obcuneiform (6 x 3 mm), divided apically into 2 very long, linear, horizontal or pendent arms: spur with its oriface wide (3 mm), with us back margin joined at the column, and with its lateral margins dilate-rounded, attenuate below the oriface and generally 2 cm long. Anther wide 2.5 mm, provided in front with short, medially excised tongue; the 2 lobes obtuse and upturned; pollina with their cauda retracted; retinacles 2 distinct and 1.2 mm long and 0.6 mm wide. Column (3 x 2 mm) auricles sub squared and very wide (1 .5 mm) median tongue of the rostellum papillous, acicular, recurved in an acute hook apically, longer than the auricles. Pedicel 1.4-1.7 cm long.

Cryptopus dissectus (Bosser) Bosser, Adansonia, n.s., 20: 261 (1980).
Homotypic Synonyms:
Cryptopus elatus subsp. dissectus Bosser, Adansonia, n.s., 5: 407 (1965).
Description:
Epiphyte with stems 30-40 cm long with roars arising along their length. Leaves 3.5-5 x 1-1.5 cm, ovate or oblong, bilobed at the apex. Inflorescence racemose, 30 cm long, 8-11-flawered; peduncle 20 cm long, stiff, sometimes divided into two. Flowers yellowish green. Sepals clawed, spathulate, 11-12 mm long, 4mm wide. Petals clawed, 14-15 mm long, the blade divided into four narrowly oblong lobes 1-2 mm wide, lip 15-17 mm long, four lobed; the two basal lobes falcate, recurved, 6-8 mm long; the two terminal lobes dissected into four narrow lobules, themselves branched at the tip. Spur 12-13mm long, funnel-shaped at the base, then filiform, the apex obtuse. Column stout, 2 mm long, auricles almost square. Anther hemispherical, with a deeply cleft lobe in front.
Notes:
Cryptopus dissectus can be distinguished from Cryptopus elatus by the smaller flowers and the deeply cut terminal lobes of the petals and lip; in Cryptopus elatus these are entire or undulate.
Habitat:
Cryptopus dissectus comes from mid-altitude, humid forest in the Fort-Carnot area of Madagascar, where it grows between 600 and 700 m.
Cultivation:
As given for the genus.
Distribution:
Mascarenes, E. Madagascar

Cryptopus paniculatus H.Perrier, Notul. Syst. (Paris) 7: 136 (1938).
Description:
Plants with very long stems (40 cm and more), generally 4 mm in diameter, pendent or flat, sheaths with 13 heavy veins, the median of which projects behind; leaves elliptical (3.5-5 x 1.3-1.8 cm), obtuse at both ends. Inflorescence paniculate (1-4 branched), 20-40 cm long, from in the sheaths; peduncle 12- 18 cm long, heating a small number of sheaths; secondary branches 5-12 cm long, bearing 3-10 apical flowers; rachis nearly sinuate; bracts obtuse and short (2 mm). Median sepal obovate (6.5-7 x 3 mm), very obtuse, attenuate toward the base from the middle, finely 3 veined; lateral sepals longer (7.5-8 mm), obtusely dilate medially on the front margin, widest apically, 2 mm. Petals larger than the sepals (9 x 12 mm between the apical lobes), in the form of an anchor, gradually enlarged above the narrow base, then dilate in 2 lateral lobes, obtuse and incurved, front margins excised; 3 veined, very divided in each lobe. Labellum inserted in front of the spur oriface, deeply 3 lobed above the short base, concave and papillous above; median lobe narrowly obtriangular, 4.5 mm long and 2 mm wide, 1 veined; lateral lobes in the form of a pick. provided basally with an obtuse, papillous callum, narrow and 6 mm tall, enlarged laterally apically in 2 equal lobes, the internal curved, the external triangular-obtuse and wider, front margins verywidely rounded; spur short (a slight 2 mm), attenuate from the oriface (with the rear margins joined with the column) apically. Ancher wide (1.8 mm), widely and deeply excised in front, with the margins angular-acute; pollina obconical with their cauda retracted, inserted in a sort of cupule; retinacles 2, hyaline. Column very short; auricles sub rectangular; median tongue of the rostellum linear, longer than the auricles. Pedicel 1.2-1.5 cm long.
Habitat:
Endemic to humid, forested slopes of eastern Madagascar between 0-1000m elevation.
Cultivation:
Cryptopus paniculatus grows well under warm or intermediate conditions with medium light (2500fc), high humidity and good air movement. It must be mounted and watered often whilst still allowing its roots to dry-off between waterings.Average daytime temperature in summer 80-83°F/26-28°C, average year-round night temperature 55°F/13°C. Flowering in February.
Distribution:
ENE. Madagascar
